Shuitu Baochi Xuebao, 2006 生态风险评价是环境、资源评价与管理方面的研究热点领域，本研究以松嫩草原西部杜蒙县为研究区域，利用该区域1979，2001，2004年3个时段的TM遥感数据、以GIS技术为数据分析平台，获取20余年不同时段的土地利用信息，研究了不同年份的土地利用类型特征。在此基础上构造一个综合性生态风险指数，然后通过系统采样、变异函数分析及空间插值对生态风险指数进行空间化，研究生态风险的空间分布特征和内在的形成机制，划分出不同风险等级区域，并有针对性的提出相应的生态风险管理措施。

Ecological Risk Assessment of Strategic Decision Making in Coastal Area [PDF]
, 2012 海岸带地处海洋与陆域的过渡区域，兼备海洋和陆域双重性质，是许多灾害和风险发生的敏感区域。然而，凭借特殊的地理位置和丰富的自然资源，海岸带地区人口迅速增长和经济快速发展，人类开发活动高度密集，使得生态系统严重退化、日益脆弱。在自然因素和人为因素的双重作用下，海岸带生态系统的安全和健康存在着巨大的潜在风险。从战略决策源头，前瞻性地将生态风险因素纳入战略决策，以期规避由于重大决策失误而造成的巨大生态风险，是预防和减少生态风险的根本途径。开展海岸带区域战略决策生态风险评价研究 ...

Selection of planning unit size in dynamic management strategies to reduce human–wildlife conflict
Conservation Biology, Volume 38, Issue 3, June 2024.Abstract Conservation planning traditionally relies upon static reserves; however, there is increasing emphasis on dynamic management (DM) strategies that are flexible in space and time. Due to its novelty, DM lacks best practices to guide design and implementation.

Ultrasound in Obstetrics &Gynecology, Volume 63, Issue 2, Page 164-172, February 2024.ABSTRACT Objective Most of the published literature on selective fetal growth restriction (sFGR) has focused on monochorionic twin pregnancies. The aim of this systematic review was to report on the outcome of dichorionic diamniotic (DCDA) twin pregnancies complicated by sFGR.

Shuitu Baochi Xuebao, 2011 通过野外采样与室内实验分析煤矸石重金属的释放活性,并利用潜在生态风险评价法分析煤矸石山周边土壤污染及其潜在生态风险特征。结果表明,实验用煤矸石中重金属主要以残渣态存在,Cu、Zn、Pb、Cr和Cd的残渣态分别占其总量的56.86%,53.27%,72.01%,68.61%和75.93%,不易发生释放迁移,但少量酸溶态和氧化物结合态重金属易被淋溶后在矸石山周围土壤中累积并造成重金属污染。煤矸石山周边土壤重金属含量随着距离的增加呈现减少趋势,表明周边土壤受到煤矸石重金属污染,并且在土壤表层重金属含量最高 ...

Ecological Risk Assessment of Coastal Engineering Planning [PDF]
, 2011 近年来，生态功能下降、珍稀濒危物种加速灭绝，一系列的生态灾害让人们意识到了生态风险评价的重要性。特别是在海岸带地区，由于其多界面相互作用，以及丰富的自然资源和密集的人类活动，致使该地区的生态系统极其脆弱。同时，海岸带工程规划往往是区域性的，包括多个开发建设项目，跨越较长时间尺度，存在累积效应，因此规划的失误将给海岸带地区带来不可估量的后果。因此，进行海岸带工程规划生态风险评价，为决策服务，具有重要的现实意义和应用价值。 本文在可持续发展原则、生态安全原则、预警原则和累积风险等原则的指导下 ...

Prenatal diagnosis and postnatal outcome of Type‐III vasa previa: systematic review of literature
Ultrasound in Obstetrics &Gynecology, Volume 63, Issue 1, Page 24-33, January 2024.ABSTRACT Objective Type‐III vasa previa (VP) is a rare form of VP, not necessarily associated with other placental or vascular anomalies, in which aberrant vessels run from the placenta to the amniotic membranes, near the internal cervical os, before returning to the placenta. Early diagnosis of Type‐III VP is important but technically challenging. The
